COLLAR BUTTON.

Application filed October 1,1923, Serial No. 665,968. Renewed January 20, 1926. V I

To aZZ whom it may concern:

Be it known that I, EDWARD G. PATTER- soN, a citizen of'the United. States, residing at Bismarck, in the county of Burleigh and State of North Dakota, have invented new and useful Improvements in. Collar Buttons, of which the following is a specification.

This invention relates to a collar button and has for its primary object the construction of a collar button thatmay be more easily arranged in place and when once in place will be positively held against'accidental IGIHOVH An object of the invention is the novel manner of associating the parts so that they may be collapsed for insertion through the button hole and theneasily extended'for locking the button in place.

With these and other objects in view the invention will be better understood from the following detailed description taken. in connection with the accompanying drawing wherein:

Fig. 1 is a side elevation of one form of.

button.

Fig. 2 is an enlarged detail view of the cam head of the links.

Fig. 3 is a side elevation partly in section of another form of my invention.- I V Again referring to the drawing illustrating two of the many constructions of my invention and more particularly to F 1 and 2 the numeral 1 designates a head that has projecting therefrom a pair of shanks 2 and 3 of a resilient 'nietal so that the shanks may be sprung away from each other. A pair of links i and 5 are provided, each having cam shaped head 5 that 1s pivotally connected to a shank as indicated at 7. It will be noted these cam shaped heads act against each other for forcing the shanks 2 and 3 apart and'this resilient action of the shanks 2 and 3 at the point of engage ment between the cam heads will allow the .ment.

shanks 4 and 5 to move into extended position as illustrated in Fig. 1. Stops 8 on the shanks limit swinging movement of the links, Thus it will be seen that in a very simple manner links may be thrown parallel to each other for easy insertion through the hole of the collar and then quickly ex tended and locked against turning move In'Figure 3 I have shown the shank 9 provided with a hollow barrel 10 in which is mounted the spring 11 acting against the collar 12 mounted on the. bar 13 to the ends of which are attached the knobs 1 f and-'15. In this particular instance the knob 1% is forced towards the shank 9 so as to extend the knob 15 to a position to be readily inserted through the hole of the collar. After the button has been inserted through the collar, knob 14 is released so thatthe spring may extend the bar a distance to one side of the shank 9 equal to the length of the barrel 10. It is of course, to be understoodv that the invention may be constructed in various other manners and the parts associated in different relations, therefore, I do not desire to be limited in any manner except as set forth inthe claim hereunto appended.

Having thus described my invention what I claim is:

A collar button comprising a head, a pair of normally parallel shanks projecting from one side of the head, a pair of retaining links pivot-ally connected to the outer ends of the shanks and adaptedlto project in longitudinal alignment therewith, or extend ed at right-angles thereto, cam shaped heads on the links at their pivot points for spreading the shanks when the links are moved to an extended position and stops on the shanks for limitingthe swinging movement of the links.

In testimony whereof I affiX my signature.

EDWARD G. PATTERSON.
